Installation InstructionsSAFETY CONSIDERATIONS

Centrifugal liquid chillers are designed to provide safeand reliable service when operated within design specifi-cations. When operating this equipment, use good judg-ment and safety precautions to avoid damage toequipment and property or injury to personnel.Be sure you understand and follow the procedures andsafety precautions contained in the machine instruc-tions, as well as those listed in this guide.

DANGER

Failure to follow these procedures will result in severe per-sonal injury or death.DO NOT VENT refrigerant relief devices within a build-ing. Outlet from rupture disc or relief valve must be ventedoutdoors in accordance with the latest edition of ANSI/ASHRAE 15 (American National Standards Institute/American Society of Heating, Refrigerating and Air-Con-ditioning Engineers) (Safety Code for Mechanical Refrig-eration). The accumulation of refrigerant in an enclosedspace can displace oxygen and cause asphyxiation.PROVIDE adequate ventilation in accordance with ANSI/ASHRAE 15, especially for enclosed and low overheadspaces. Inhalation of high concentrations of vapor is harm-ful and may cause heart irregularities, unconsciousness, ordeath. Intentional misuse can be fatal. Vapor is heavier thanair and reduces the amount of oxygen available for breath-ing. Product causes eye and skin irritation. Decompositionproducts are hazardous.DO NOT USE OXYGEN to purge lines or to pressurize amachine for any purpose. Oxygen gas reacts violently withoil, grease, and other common substances.DO NOT USE air to leak test. Use only refrigerant or drynitrogen.NEVER EXCEED specified test pressures. VERIFY theallowable test pressure by checking the instruction litera-ture and the design pressures on the equipment nameplate.DO NOT VALVE OFF any safety device.BE SURE that all pressure relief devices are properlyinstalled and functioning before operating any machine.RISK OF INJURY OR DEATH by electrocution. Highvoltage is present on motor leads even though the motor isnot running when a solid state or inside-delta mechanicalstarter is used. Open the power supply disconnect beforetouching motor leads or terminals.

WARNING

Failure to follow these procedures may result in personalinjury or death.DO NOT USE TORCH to remove any component. Systemcontains oil and refrigerant under pressure. To remove a component, wear protective gloves and gog-gles and proceed as follows:a. Shut off electrical power to unit.b. Recover refrigerant to relieve all pressure from sys-

tem using both high-pressure and low pressure ports.c. Traces of vapor should be displaced with nitrogen

and the work area should be well ventilated. Refrig-erant in contact with an open flame produces toxicgases.

d. Cut component connection tubing with tubing cutterand remove component from unit. Use a pan to catchany oil that may come out of the lines and as a gagefor how much oil to add to the system.

e. Carefully unsweat remaining tubing stubs when nec-essary. Oil can ignite when exposed to torch flame.

DO NOT USE eyebolts or eyebolt holes to rig machinesections or the entire assembly.DO NOT work on high-voltage equipment unless you are aqualified electrician.DO NOT WORK ON electrical components, includingcontrol panels, switches, starters, or oil heater until you aresure ALL POWER IS OFF and no residual voltage canleak from capacitors or solid-state components.LOCK OPEN AND TAG electrical circuits during servic-ing. IF WORK IS INTERRUPTED, confirm that all cir-cuits are de-energized before resuming work.AVOID SPILLING liquid refrigerant on skin or getting itinto the eyes. USE SAFETY GOGGLES. Wash any spillsfrom the skin with soap and water. If liquid refrigerantenters the eyes, IMMEDIATELY FLUSH EYES withwater and consult a physician.NEVER APPLY an open flame or live steam to a refriger-ant cylinder. Dangerous over pressure can result. When it isnecessary to heat refrigerant, use only warm (110 F [43 C])water.DO NOT REUSE disposable (nonreturnable) cylinders orattempt to refill them. It is DANGEROUS AND ILLE-GAL. When cylinder is emptied, evacuate remaining gaspressure, loosen the collar, and unscrew and discard thevalve stem. DO NOT INCINERATE.CHECK THE REFRIGERANT TYPE before addingrefrigerant to the machine. The introduction of the wrongrefrigerant can cause machine damage or malfunction.(Warnings continued on next page.)

Step 1 — Receive the MachineINSPECT SHIPMENT

1. Inspect for shipping damage while machine is still onshipping conveyance. If machine appears to be damagedor has been torn loose from its anchorage, have itexamined by transportation inspectors before removal.

WARNING

Operation of this equipment with refrigerants other thanthose cited herein should comply with ANSI/ASHRAE 15(latest edition). Contact Carrier for further information onuse of this machine with other refrigerants.DO NOT ATTEMPT TO REMOVE fittings, covers, etc.,while machine is under pressure or while machine is run-ning. Be sure pressure is at 0 psig (0 kPa) before breakingany refrigerant connection.CAREFULLY INSPECT all relief valves, rupture discs,and other relief devices AT LEAST ONCE A YEAR. Ifmachine operates in a corrosive atmosphere, inspect thedevices at more frequent intervals.DO NOT ATTEMPT TO REPAIR OR RECONDITIONany relief valve when corrosion or build-up of foreignmaterial (rust, dirt, scale, etc.) is found within the valvebody or mechanism. Replace the valve.DO NOT install relief devices in series or backwards.USE CARE when working near or in line with a com-pressed spring. Sudden release of the spring can cause itand objects in its path to act as projectiles.

CAUTION

Failure to follow these procedures may result in damage toequipment.DO NOT STEP on refrigerant lines. Broken lines can whipabout and release refrigerant, causing personal injury.DO NOT climb over a machine. Use platform, catwalk, orstaging. Follow safe practices when using ladders.USE MECHANICAL EQUIPMENT (crane, hoist, etc.) tolift or move inspection covers or other heavy components.Even if components are light, use mechanical equipmentwhen there is a risk of slipping or losing your balance.BE AWARE that certain automatic start arrangementsCAN ENGAGE THE STARTER, TOWER FAN, ORPUMPS. Open the disconnect ahead of the starter, towerfan, and pumps. Shut off the machine or pump before ser-vicing equipment.USE only repaired or replacement parts that meet the coderequirements of the original equipment.DO NOT VENT OR DRAIN waterboxes containingindustrial brines, liquid, gases, or semisolids without thepermission of your process control group.DO NOT LOOSEN waterbox cover bolts until the water-box has been completely drained.DOUBLE-CHECK that coupling nut wrenches, dial indi-cators, or other items have been removed before rotatingany shafts.DO NOT LOOSEN a packing gland nut before checkingthat the nut has a positive thread engagement.PERIODICALLY INSPECT all valves, fittings, and pipingfor corrosion, rust, leaks, or damage.PROVIDE A DRAIN connection in the vent line near eachpressure relief device to prevent a build-up of condensateor rain water.DO NOT re-use compressor oil or any oil that has beenexposed to the atmosphere. Dispose of oil per local codesand regulations. DO NOT leave refrigerant system open to air any longerthan the actual time required to service the equipment. Sealcircuits being serviced and charge with dry nitrogen to pre-vent oil contamination when timely repairs cannot be com-pleted.

CAUTION

Do not open any valves or loosen any connections. The19XR, 19XRV machine may be shipped with a nitrogenholding charge in both modules. Damage to machine mayresult.

Forward claim papers directly to transportation company.Manufacturer is not responsible for any damage incurredin transit.

2. Check all items against shipping list. Immediately notifythe nearest Carrier representative if any item is missing.

3. To prevent loss or damage, leave all parts in originalpackages until beginning installation. All openings areclosed with covers or plugs to prevent dirt and debrisfrom entering machine components during shipping. Afull operating oil charge is placed in the oil sump beforeshipment.

IDENTIFY MACHINE — The machine model number, seri-al number, and heat exchanger sizes are stamped on machineidentification nameplate (Fig. 1-3). Check this informationagainst shipping papers and job data.

INSTALLATION REQUIREMENTS — Prior to starting thechiller’s electrical installation, certain requirements should bechecked. Input power wire sizes, branch circuit protection, andcontrol wiring are all areas that need to be evaluated.Determine Wire Size Requirements — Wire size should bedetermined based on the size of the conduit openings, andapplicable local, national, and international codes (e.g., NEC

[National Electric Code]/CEC [California Energy Commis-sion] regulations). General recommendations are included inthe Carrier field wiring drawings.Conduit Entry Size — It is important to determine the size ofthe conduit openings in the enclosure power entry plate so thatthe wire planned for a specific entry point will fit through theopening. Do NOT punch holes or drill into the top surface ofstarter or drive if knockouts are provided on the side of the en-closure and not the top of the enclosure.Recommended Control and Signal Wire Sizes — The rec-ommended minimum size wire to connect I/O signals to thecontrol terminal blocks is 18 AWG (American Wire Gage).Recommended terminal tightening torque is 7 to 9 in.-lb(0.79 to 1.02 N-m).Recommended Airflow Clearances — Be sure there is ade-quate clearance for air circulation around the enclosure.A 6-in. (152.4 mm) minimum clearance is required wherevervents are located in the starter or drive enclosure.Verify Adequate Power Supply — It is important to verifythat the building power will meet the input power requirementsof the Machine Electrical Data nameplate input power rating.Be sure the input power to the chiller corresponds to the chill-er’s nameplate voltage, current, and frequency.PROVIDE MACHINE PROTECTION — Store machineand starter indoors, protected from construction dirt and mois-ture. Inspect under shipping tarps, bags, or crates to be sure thatwater has not collected during transit. Keep protective shippingcovers in place until machine is ready for installation.

If machine is exposed to freezing temperatures after watercircuits have been installed, open waterbox drains and removeall water from cooler and condenser. Leave drains open untilsystem is filled.

Step 2 — Rig the Machine — The 19XR, 19XRVmachine can be rigged as an entire assembly. It also has flangedconnections that allow the compressor, cooler, and condensersections to be separated and rigged individually.RIG MACHINE ASSEMBLY — See rigging instructions onlabel attached to machine. Refer to rigging guide (Fig. 4-6),physical data in Fig. 7, and Tables 1-8B. Lift machine only fromthe points indicated in rigging guide. Each lifting cable orchain must be capable of supporting the entire weight of themachine.Contractors are not authorized to disassemble any part of thechiller without Carrier's supervision. Any request otherwisemust be in writing from the Carrier Service Manager.NOTE: Carrier suggests that a structural engineer be consultedif transmission of vibrations from mechanical equipment is ofconcern.

Step 3 — Install Machine SupportsINSTALL STANDARD ISOLATION — Figures 12 and 13show the position of support plates and shear flex pads, whichtogether form the standard machine support system.

INSTALL ACCESSORY ISOLATION (if required) — Un-even floors or other considerations may dictate the use ofaccessory soleplates (supplied by Carrier for field installation)and leveling pads. Refer to Fig. 12 and 14.

Level machine by using jacking screws in isolation sole-plates. Use a level at least 24-in. (600 mm) long.

For adequate and long lasting machine support, propergrout selection and placement is essential. Carrier recommendsthat only pre-mixed, epoxy type, non-shrinking grout be usedfor machine installation. Follow manufacturer’s instructions inapplying grout.

1. Check machine location prints for required groutthickness.

2. Carefully wax jacking screws for easy removal fromgrout.

3. Grout must extend above the base of the soleplate andthere must be no voids in grout beneath the plates.

4. Allow grout to set and harden, per manufacturer’s in-structions, before starting machine.

5. Remove jacking screws from leveling pads after grouthas hardened.

IMPORTANT: Chiller housekeeping pad, anchor bolts, andattachment points that are designed by others must be inaccordance with all applicable national and local codes.

INSTALL VENT PIPING TO RELIEF VALVES — The19XR, 19XRV chiller is factory equipped with relief valves onthe cooler and condenser shells. Refer to Fig. 25 and Tables 10and 11 for size and location of relief devices. Vent reliefdevices to the outdoors in accordance with ANSI/ASHRAE 15(latest edition) Safety Code for Mechanical Refrigeration andall other applicable codes.

1. If relief devices are manifolded, the cross-sectional areaof the relief pipe must at least equal the sum of the areasrequired for individual relief pipes.

2. Provide a pipe plug near outlet side of each relief devicefor leak testing. Provide pipe fittings that allow vent

piping to be disconnected periodically for inspection ofvalve mechanism.

3. Piping to relief devices must not apply stress to the de-vice. Adequately support piping. A length of flexible tub-ing or piping near the device is essential on spring-isolated machines.

4. Cover the outdoor vent with a rain cap and place a con-densation drain at the low point in the vent piping to pre-vent water build-up on the atmospheric side of the reliefdevice.

Step 5 — Make Electrical Connections — Fieldwiring must be installed in accordance with job wiring dia-grams and all applicable electrical codes.

Wiring diagrams in this publication (Fig. 26-35) are for ref-erence only and are not intended for use during actual installa-tion; follow job specific wiring diagrams.

CONNECT CONTROL INPUTS — Wiring may be speci-fied for a spare safety switch, and a remote start/stop contactcan be wired to the starter terminal strip. Additional spare sen-sors and Carrier Comfort Network modules may be specifiedas well. These are wired to the machine control panel as indi-cated in Fig. 26. The PIC II control panel optional wiring andpower panel component layout is shown in Fig. 27.

CONNECT CONTROL OUTPUTS — Connect auxiliaryequipment, chilled and condenser water pumps, and sparealarms as required and indicated on job wiring drawings.CONNECT STARTER — The 19XR chiller is available witha unit-mounted, factory-installed starter or VFD (variable fre-quency drive) (Fig. 28-30) or a free-standing, field-installedstarter or VFD (Fig. 32-35).Unit-Mounted, Factory-Installed Starter or VFD — Attachpower leads by connecting them from inside the starter cabinetto the line side circuit breaker terminals. See Fig. 28-31.

Machines with electro-mechanical starters (wye-delta) willhave a top hat shipped with the machine if the RLA (rated loadamps) is greater than 935 amps. If the machine is equipped

with a solid-state starter, a top hat is provided if the RLAexceeds 740 amps. The top hat is shipped in the knocked-downposition and must be assembled and installed on top of thestarter cabinet, over the line side circuit breaker. Duringassembly, remove the access plate and use it as the cover pieceof the top hat. The top hat provides additional wire bendingspace to attach line side power leads to the circuit breakerwithin the starter.

IMPORTANT: Be sure to ground the power circuit inaccordance with the National Electrical Code (NEC),applicable local codes, and job wiring diagrams. Also,make sure correct phasing is observed for proper rotation.

NOTES FOR FIG. 2919XR with Unit-Mounted Starter

I. GENERAL1.0 Starters shall be designed and manufactured in accordance

with Carrier Engineering Requirement Z-415.1.1 All field-supplied conductors, devices, and the field-

installation wiring, and termination of conductors anddevices, must be in compliance with all applicable codesand job specifications.

1.2 The routing of field-installed conduit and conductors andthe location of field-installed devices must not interfere withequipment access or the reading, adjusting, or servicing ofany component.

1.3 Equipment installation and all starting and control devices,must comply with details in equipment submittal drawingsand literature.

1.4 Contacts and switches are shown in the position they wouldassume with the circuit de-energized and the chiller shutdown.

1.5 WARNING — Do not use aluminum conductors.1.6 Installer is responsible for any damage caused by improper

wiring between starter and machine.II. POWER WIRING TO STARTER

2.0 Provide a means of disconnecting power to starter.2.1 Power conductor rating must meet minimum unit nameplate

voltage and compressor motor FLA (minimum circuitampacity).

2.2 Lug adapters may be required if installation conditions dic-tate that conductors be sized beyond the minimum ampac-ity required. Breaker lugs will accommodate the quantity (#)and size (MCM) cables (per phase) as indicated in tablesbelow.

2.3 Power conductors to starter must enter through top ofenclosure. Flexible conduit should be used for the last fewfeet to the enclosure to provide unit vibration isolation.

2.4 Compressor motor and controls must be grounded by usingequipment grounding lugs provided inside unit-mountedstarter enclosure.

2.5 Starters with “Rated Load Amps” (RLA) greater than 433Arequire the assembly and the installation of a “Top Hat”(located inside enclosure) to provide the required wirebending space for incoming power leads.

2.6 Metering current transformers (CTs), if present, have aninner diameter of 23/4 in. Caution should be taken whenselecting power wiring so that all power cables can passthrough the CTs.

III. CONTROL WIRING3.0 Field supplied control conductors to be at least 18 AWG or

larger.3.1 Ice build start/terminate device contacts, remote start/stop

device contacts and spare safety device contacts (devicesnot supplied by Carrier), must have 24 VAC rating. MAXcurrent is 60 mA, nominal current is 10 mA. Switches withgold plated bifurcated contacts are recommended.

3.2 Remove jumper wire between J2-1 and J2-2 before con-necting auxiliary safeties between these terminals.

3.3 Each integrated contact output can control loads (VA) forevaporator pump, condenser pump, tower fan low, tower fanhigh, and alarm annunciator devices rated 5 amps at 115VAC and up to 3 amps at 277 VAC.

Do not use control transformers in the control center as thepower source for external or field-supplied contactor coils,actuator motors or any other loads.

3.4 If one single speed fan is used, connect fan control leadsJ9-13 and -14, jumper ISM J9-13 to -11, and jumper J9-14to -12. This will allow the fan to be actuated by closure ofeither “low fan” or “high fan” ISM channel contact.

3.5 Do not route control wiring carrying 30 v or less within aconduit which has wires carrying 50 v or higher or alongside wires carrying 50 v or higher.

3.6 Control wiring between starter and power panel must be sepa-rate shielded cables with minimum rating of 600 v, 80 C.Ground shield at starter.

3.7 Spare 4-20 mA output signal is designed for controllers with anon-grounded 4-20 mA input signal and a maximum inputimpedance of 500 ohms.

3.8 Flow devices to confirm evaporator or condenser pump floware not required. However; if flow devices are used, wire asshown in diagram below. Remove jumper installed at theseterminals and wire in a 4.3 K resistor in its place. The flowdevice and resistor must be installed in parallel at these termi-nals such that the resistor provides a signal when the flowdevice is open.

CAUTION

To prevent damage to machine, do NOT punch holes or drill intothe top surface of the starter enclosure for field wiring. Knock-outs are provided on the side of the starter enclosure for fieldwiring connections.

Free-Standing, Field-Installed Starter or VFD — Assembleand install compressor terminal box in desired orientation, andcut necessary conduit openings in conduit support plates. SeeFig. 32-35. Attach power leads to compressor terminals in ac-cordance with job wiring drawings, observing caution label interminal box. Use only copper conductors. The motor must begrounded in accordance with NEC (National Electrical Code),applicable local codes, and job wiring diagrams. Installer is re-sponsible for any damage caused by improper wiring betweenstarter and compressor motor.

Insulate Motor Terminals and Lead Wire Ends — Insulatecompressor motor terminals, lead wire ends, and electricalwires to prevent moisture condensation and electrical arcing.For low-voltage units (up to 600 v), obtain insulation materialfrom machine shipping package consisting of 3 rolls of insula-tion putty and one roll of vinyl tape.

1. Insulate each terminal by wrapping with one layer of in-sulation putty.

2. Overwrap putty with 4 layers of vinyl tape.High Voltage Units — High-voltage units require special ter-minal preparation. Follow local electrical codes for high-volt-age installation. Vinyl tape is not acceptable; a high voltageterminal method must be used.

IMPORTANT: Do not insulate terminals until wiringarrangement has been checked and approved by Carrierstart-up personnel. Also, make sure correct phasing is fol-lowed for proper motor rotation.

Connect Power Wires to Oil Pump Starter — See Fig. 36.Connect power wires to oil pump starter mounted in machinepower panel. Use separate fused disconnect or circuit breakeras shown on job wiring diagrams and Fig. 36. Check thatpower supply voltage agrees with oil pump voltage. Followcorrect phasing for proper motor rotation.

Connect Power Wires to Oil Heater Contactor — Connectcontrol power wiring between the oil heater contactor termi-nals and terminals LL1 and LL2 on the field wiring strip in thecompressor motor starter. Refer to Fig. 37 and wiring label onthe machine power panel for units without split ring diffuser.Refer to Fig. 38 for units with split ring diffuser.

Connect Wiring from Starter to Power Panel — Connect con-trol wiring from main motor starter to the machine powerpanel. All control wiring must use shielded cable. Also, con-nect the communications cable. Refer to the job wiring dia-grams for cable type and cable number. Make sure the controlcircuit is grounded in accordance with applicable electricalcodes and instructions on machine control wiring label.CARRIER COMFORT NETWORK INTERFACE — TheCarrier Comfort Network® (CCN) communication bus wiringis supplied and installed by the electrical contractor. It consistsof shielded, 3-conductor cable with drain wire.

The system elements are connected to the communicationbus in a daisy chain arrangement. The positive pin of each sys-tem element communication connector must be wired to thepositive pins of the system element on either side of it. Thenegative pins must be wired to the negative pins. The signalground pins must be wired to the signal ground pins. SeeFig. 26 for location of the CCN network connections on the ter-minal strip labelled CCN.NOTE: Conductors and drain wire must be 20 AWG (Ameri-can Wire Gage) minimum stranded, tinned copper. Individualconductors must be insulated with PVC, PVC/nylon, vinyl,Teflon, or polyethylene. An aluminum/polyester 100% foilshield and an outer jacket of PVC, PVC/nylon, chrome vinyl,or Teflon with a minimum operating temperature range of –4 Fto 140 F (–20 C to 60 C) is required. See table below for cablesthat meet the requirements.

When connecting the CCN communication bus to a systemelement, a color code system for the entire network is recom-mended to simplify installation and checkout. The followingcolor code is recommended:

If a cable with a different color scheme is selected, a similarcolor code should be adopted for the entire network.

CAUTION

Do not punch holes or drill into the top surface of eitherpower panel. Knockouts are provided in the bottom of thepower panels for wiring connections. Damage to machinecould result.

WARNING

Voltage to terminals LL1 and LL2 (of each circuit) comesfrom a control transformer in a starter built to Carrier speci-fications. Do not connect an outside source of controlpower to the compressor motor starter (terminals LL1 andLL2 of each circuit). An outside power source will producedangerous voltage at the line side of the starter, becausesupplying voltage at the transformer secondary terminalsproduces input level voltage at the transformer primary ter-minals. Severe injury could result.

At each system element, the shields of its communicationbus cables must be tied together. If the communication bus isentirely within one building, the resulting continuous shieldmust be connected to ground at only one single point. SeeFig. 26. If the communication bus cable exits from one build-ing and enters another, the shields must be connected to groundat the lightening suppressor in each building where the cableenters or exits the building (one point only).

To connect the 19XR chiller to the network, proceed as fol-lows (see Fig. 26):

1. Route wire through knockout in back of control panel.2. Strip back leads.3. Crimp one no. 8 size spring spade terminal on each

conductor.4. Attach red to “+” terminal and white to “G” terminal and

black to “–” terminal of CCN Network interface locatedin the control panel.

OPTIONAL UPC OPEN CONTROLLER WIRING — Theoptional UPC Open controller communicates using BACnet*on an MS/TP network segment communications at 9600 bps,19.2 kbps, 38.4 kbps, or 76.8 kbps.

Wire the controllers on an MS/TP network segment in a dai-sy-chain configuration. Wire specifications for the cable are22 AWG (American Wire Gage) or 24 AWG, low-capacitance,twisted, stranded, shielded copper wire. The maximum lengthis 2000 ft.

Install a BT485 terminator on the first and last controller ona network segment to add bias and prevent signal distortionsdue to echoing. See Fig. 39-41.

To wire the UPC Open controller to the BAS network:1. Pull the screw terminal connector from the controller's

BAS Port.2. Check the communications wiring for shorts and

grounds.3. Connect the communications wiring to the BAS port’s

screw terminals labeled Net +, Net -, and Shield.NOTE: Use the same polarity throughout the networksegment.

4. Insert the power screw terminal connector into the UPCOpen controller's power terminals if they are not current-ly connected.

5. Verify communication with the network by viewing amodule status report. To perform a module status reportusing the BACview keypad/display unit, press and holdthe “FN” key then press the “.” Key.

To install a BT485 terminator, push the BT485, on to theBT485 connector located near the BACnet connector.NOTE: The BT485 terminator has no associated polarity.

To order a BT485 terminator, consult Commercial Productsi-Vu® Open Control System Master Prices.MS/TP Wiring Recommendations — Recommendations areshown in Tables 12 and 13. The wire jacket and UL tempera-ture rating specifications list two acceptable alternatives. TheHalar specification has a higher temperature rating and atougher outer jacket than the SmokeGard specification, and it isappropriate for use in applications where the user is concernedabout abrasion. The Halar jacket is also less likely to crack inextremely low temperatures. NOTE: Use the specified type of wire and cable for maximumsignal integrity.
